RAIL-ANCHOR).

Application filed August- 27, 1917. Serial; 1T0. 188,276.

To all whom it may concern: v

Be it known that I, JACOB J. BYERS, av citizen of the United States, and a resident of Chicago, Cook county, Illinois, have 1nvented new and useful Improvements in Rail-Anchors, of which the following is a specification, reference being bad to the accompanying drawings, in which:

Figure l is a plan of. a rail anchor em-.

bodying my invention, showing the parts in position to be applied to the rail; F 1g. 2 is an elevation thereof, with the rail in cross section; Fig. 3 is a plan showing the parts locked to the rail; Fig. 4 is a detail thereof, and Fig. 5 is a section on the lines V-V of Fig. 3.

My invention relates to rail anchors and consists in a base member and in a spring clamp by the action of which the anchor is securely fastened to the rail. My invention also consists in the construction and arrangement of parts which I shall hereinafter describe and claim.

' Referring to the drawings, the anchor consists in the base or body member A and in the spring clamp B. The base member A has at one end a rail flange engag ng aw 2, and adjacent thereto is a depending abut ment 3, intended to engage a tie. At the opposite end of the member A is a remforced portion 4, which has a vertlcal socket 5 therein adapted to receive the beveled edge 6 of the clamp B. The clamp B may be,

made of spring steel and has a rail base engaging j aw 7 on the inner face'thereof. The lower end 8 of the clamp B is bent substantially at right angles to the vertically-disposed"body of the clamp and ispreferably cut off at an angle thereto.

The anchor is applied to a rail by placing the member A beneath the rail with the jaw 2 engaging one base flange of the rail with the abutment 3 against a tie. The spring clamp B is placed in the position shown in Fig. 1, with its jaw engaging a base flange of the rail and with its edge 6 in the socket 5. The clamp may then be twisted by means of a wrench into the locked position shown in Fig. 3, in which position the clamp lies Specification of Letters: Patent.

of the rail.

toward the tie so that the body of the anchor does not lie at right angles to the longitudinal axis of the rail as it did before applying the clamp. If desired, in order to provide a take-up for variations in dimensions of the rail and of the two'parts of the anchor the entire anchor may be twisted still more upon the rail by sledging the clamp ing end a little nearer to the. tie.

The base member A has a downwardlyinclined surface 10 below which thelower end 8 of the clamp B lies, and as the clamp is turned in looking the end 8 rides down the surface 10, drawing the clamp and base member very tightly against the base flanges The drawing-down action springs the end 8 of the clamp very slightly, so as to give the clamp a spring grip upon the rail, which is not loosened by vibration.

The downward pressure as it is exerted at the right angled lower end of the clamp has also atendency to tip the clamp slightly out of the perpendicular, so that the edges of the 'jaw 7 bite into the'rail flange and exert an additio-nal hold upon the rail. The tie abutment 3 has an inclined face 11 so that, as the rail begins to creep, the increased pressure of the abutment against the tie will exert a tilting action upon the anchor, thus causing the jaws 2 and 7 to bite more firmly into the rail and resist the creeping action.

The terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any mechanical equivalents of thefeatures shown and described, or portions thereof, but recognize that various modifications are possible. within the scope of the invention claimed.

What I claim is 1. In a rail anchor, a pair of members having a rotative engagement about a vertical axis, each having a rail flange receiving jaw, one of said members having a convex surface on its under side and the other of said members having a concave surface adapted to cooperate with the convex surface to draw down the jaw on the last mentioned member upon a rail flange.

2. In a rail anchor, a spring clamp, a base member having on one side a rail flange receiving jaw and on the other a socket for the spring clamp; the clamp having a bearing in the socket, a rail flange receiving jaw and an angled portion engaging an inclined surface on the base member.

3. In a rail anchor, a base member hav-' ing on one side a rail flange receiving jaw and on the other a vertically-disposed socket, a spring clamp having a bearing adapted to fit in the said socket, and a rail flange receiving jaw, the spring clamp being adapted to be rotated into position to force the jaws to clamp on the rail.

4:. In a rail anchor, a base member having on one side a rail flange receiving jaw and on the other a reinforced portion, the reinforced portion having a vertically-disposed socket on the inner face thereof, a spring clamp having on its outer face a bearing seating in said socket and on its inner face a rail receiving jaw and being adapted to be rotated in said socket into a locking engagement with the base flange of a rail.

5. In a rail anchor, a base member adapted to extend beneath a rail and having at one end a jaw for the reception of one base flange of the rail'and at the other a socket, a spring clamp seating in said socket having a jaw adapted to be rotated into engagement with the other base flange of the rail, and a tie abutment adapted to tilt the anchor about its long axis and cause the jaws to bite into the base flanges.

6. In a rail anchor, a pair of members having a rotative engagement, each having a jaw engaging the upper and lower faces of a rail flange, one of said members having a convex surface on its under side and the other of said members having a concave surface adapted to cooperate with the convex surface to draw down the jaw on the last-mentioned member upon a rail flange.
